Deducting fees without consent

I was sent a fine from Alamo, that included the fine amount as well as a “redirection fee” of R287.50. I had paid the fine prior to receiving this invoice from Alamo, as I was in the position of the original fine. I sent the proof of payment as well as the original fine, to which I received a response “thank you, noted”. A couple of days later, Alamo deducted the amount from my credit card, without authorisation. I emailed the individual who had said “thank you, noted”, who never bothered to reply. I then lodged a complaint on Alamo’s website, three weeks ago, and never received a response or any correspondence from Alamo. Disgusting service. Will never hire from them again.
